초록 ▼

A gas turbine engine annular combustor having a bulkhead at its upstream end which is thermally protected by an annular array of heat shields. Each heat shield is provided with integral flanges which space apart the heat shields and bulkhead to define chambers therebetween. Apertures in the bulkhead direct cooling air into the chambers. Further apertures in the heat shields exhaust the cooling air in a common circumferential direction so that the air flows merge to define a substantially continuous annular flow of cooling air about the longitudinal axis of the combustor and across the downstream heat shield faces.

대표청구항 ▼

A gas turbine engine annular combustor including a bulkhead at its upstream end, said bulkhead having a plurality of fuel burner receiving apertures therein, a plurality of heat shields, said heat shields being located on the downstream face of said bulkhead so as to provide thermal shielding of said bulkhead, said heat shields being arranged in an annular array, means being provided to space apart each of said heat shields and said bulkhead so that corresponding chambers are defined therebetween and including, for each said heat shield, a plurality of bolts extending from the upstream face thereof for attachment to the bulkhead of the combustor, said bolts each being spaced from an adjacent edge of each respective heat shield, said bulkhead having a plurality of further apertures therein to direct cooling air into said chambers, each of said heat shields having a plurality of cooling air apertures therein which are adapted to exhaust cooling air from its associated chamber, at least some of said cooling air apertures being located in an array adjacent the radially outer extents of each of said heat shields and being substantially uniformly spaced in a continuous manner about the circumference of said combustor, the array being without any discontinuities in said array in a circumferential direction, each of said at least some of said apertures having an axis inclined to exhaust cooling air in a common generally circumferential direction so that said cooling air flows from said at least some of said cooling air apertures merge to define at least one substantially continuous annular flow of cooling air about the longitudinal axis of said combustor and circumferentially across the downstream faces of said heat shields
